Desktop/horizontal. Of course, I have 5 minitowers and 1 desktop - it's been really hard to find cases (other than $150 eBay specials with rust and/or bad photos).
Better/cheaper 3D printing may eventually solve this for me and others - though some of the nicer cases from back in the day were a little complex (Everex Step with the info/control panel, for example, or Compaqs).
Eventually it'll be harder to get the back portion of the case made - but if enough people want them someone could do a run of "universal AT cases" for the metal only, make/provide your own front plastic. That would be nice - but probably expensive.
For modern computers, a mid-size tower is easier to get out of the way. My main desktop and file server are on shelves next to my desk.
